34 INFRASTRUCTURE AUSTRALIA APRIL 2010
Rail
Adelaide s metropolitan rail
network is about to undergo
extension and modernisation
after planning, concept
design and environmental assessments
were completed in January.
Concept designs have been complet-
ed for an extension of the rail line from
Noarlunga to Seaford, with associated
stations and park and ride facilities. e
$291 million project will improve public
transport services to Adelaide s rapidly
growing southern suburbs.
e South Australian Department of
Infrastructure, Transport, Regional De-
velopment and Local Government said
major design and construction works
on the extension are expected to start
in September with electric train services
to start operating in 2013, in line with
the completion of electri cation of the
Noarlunga line.
e Seaford Rail Extension project
will provide a 5.5km extension of the
dual track rail line from Noarlunga
centre railway station to the Seaford dis-
trict centre. It will see the construction
of stations at Seaford Meadows and the
Seaford rail terminus and a 1.2km via-
duct and bridge over the Onkaparinga
River. A park and ride facility at Seaford
Meadows as well as a bus interchange at
the Seaford district centre will also be
included.
Providing a rail service to the Seaford
district centre is expected to reduce
public transport travel times by up to
10min on a trip to Adelaide. is service
is expected to attract approximately 6000
public transport trips per weekday and
around 1.7 million trips per annum. e
existing rail line to Noarlunga has the
second highest patronage with only the
Gawler line having greater patronage.
is project, along with another that
will see the Gawler rail line renewed,
is part of a strategic plan by the South
Australian government to improve and
modernise public transport service
across Adelaide s metropolitan rail
network.
e Gawler line carries around 34%
of Adelaide s rail passengers and the state
government is investing $294 million to
resleeper and electrify the 43km Gawler
line, north of Adelaide s central business
district.
Planning progresses in Adelaide
Aregional Victorian rail project is on track for
completion in the second half of the year with major
civil works nearing completion and the laying of tracks
due to have commenced this month.
e North East Rail Revitalisation project is seeing the con-
struction of a rail bypass of Wodonga and an upgrade of the track
between Melbourne and Albury-Wodonga. e project will cre-
ate an "interstate rail freight super-highway" and deliver major
improvements to passenger services.
e project involves construction of a 5km dual track rail
bypass of Wodonga, enabling the removal of the rail line and 11
level crossings from the city centre. A new train station is under
construction at West Wodonga while new platforms are being
built between Broadmeadows and Albury-Wodonga.
e Victorian Department of Transport said that the six rail
bridges and one road bridge involved in the project are all near-
ing completion. is will allow for works to commence on the
laying of tracks.
A 200km section of track is also being upgraded and stan-
dardised, by converting from broad gauge to standard gauge
between Seymour and Albury-Wodonga, and replacing timber
sleepers with concrete sleepers. e Victorian department of trans-
port said most of this work has been completed, with more than
500,000 new concrete sleepers already laid on rail line between
Melbourne and Sydney.
On top of this, four new passing loops are being constructed
and the standard gauge line between Seymour and Melbourne is
being upgraded. Also, a number of V/Line trains are being refur-
bished and converted to standard gauge, and a new train mainte-
nance facility for these trains is under construction in Melbourne.
Another facet of the project is the upgrade of signalling along
the line. e Victorian department of transport said that marry-
ing the new and existing signalling systems has been a signi cant
challenge, particularly at the border into NSW.
e project is jointly funded by the federal government, the
Victorian government and Australian Rail Track Corporation.
It is being delivered by the South Improvement Alliance (SIA),
comprising John Holland Rail, MVM Rail and O Donnell Gri n
together with the Australian Rail Track Corporation. e alliance
also includes sub-alliance partners Kellogg Brown & Root and
Aure c on.
e project commenced in 2008 and is due for completion
later this year.
Standardising a major rail corridor
The new Wodonga bypass route will remove 11 level crossings from the city
centre, improving services on Victoria s northeast rail corridor.
